Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

Paul and his cousin are playing a game where they pick up colored sticks. Paul currently has 21 points and likes to pick up the indigo sticks, earning 4 points every turn. His cousin just lost all his points on the previous turn, and has a strategy to catch up by getting all the green ones, earning 7 points per turn. In a certain number of turns, the score will be tied. How long will that take? How many points will they each have?


In turns, both players will have points.
